Usando apache2 en el servidor Ubuntu 22.04.

El certificado letsencrypt incluye:example.com, www.example.com and mail.example.com
Existe el siguiente error en los registros:

¿Alguna idea de por qué https mail.example.comel host predeterminado lo detecta en lugar del dominio?
Actualizar
Aquí hay una salida deapachectl -D DUMP_VHOSTS
VirtualHost configuration:
*:443 is a NameVirtualHost
default server mail.example.com (/etc/apache2/sites-enabled/0-default-ssl.conf:2)
port 443 namevhost mail.example.com (/etc/apache2/sites-enabled/0-default-ssl.conf:2)
port 443 namevhost example.com (/etc/apache2/sites-enabled/example.com-ssl.conf:2)
wild alias *.example.com
*:80 is a NameVirtualHost
default server mail.example.com (/etc/apache2/sites-enabled/0-default.conf:1)
port 80 namevhost mail.example.com (/etc/apache2/sites-enabled/0-default.conf:1)
port 80 namevhost example.com (/etc/apache2/sites-enabled/example.com.conf:1)
wild alias *.example.com
Entonces probablemente la pregunta debería ser: ¿por qué se considera mail.example.comel nombre del servidor predeterminado? ¿Podría ser el PTR mail.example.comel motivo?
